STATEMENT REGARDING PRIOR DISCLOSURES BY INVENTOR & APPLICANT/ASSIGNEE

The Inventor and Applicant/Assignee assert that no publications nor advertisements relating to sales, offers for sale or public distribution occurred more than one year prior to the effective filing date of this application. Any information about the claimed plant would have been obtained from a direct or indirect disclosure from the Inventor and/or Applicant/Assignee. Inventor and Applicant/Assignee claim a prior art exception under 35 U.S.C. 102(b)(1) for disclosure and/or sales prior to the filing date but less than one year prior to the effective filing date.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of New Guinea Impatiens plant, botanically known as Impatiens hawkeri and hereinafter referred to by the name ‘Dongimagmior’.

The new Impatiens plant is a product of a planned breeding program conducted by the Inventor in Koka, Ethiopia and Encinitas, Calif. The objective of the breeding program is to create new freely branching and early and freely flowering New Guinea Impatiens plants with large attractive flowers and good garden performance.

The new Impatiens plant originated from a cross-pollination made by the Inventor in November, 2016 in Koka, Ethiopia of a proprietary selection of Impatiens hawkeri identified as code number NN15-735717-002, not patented, as the female, or seed, parent with a proprietary selection of Impatiens hawkeri identified as code number NN07-001623-005, not patented, as the male, or pollen, parent. The new Impatiens plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Encinitas, Calif. in April, 2017.

Asexual reproduction of the new Impatiens plant by terminal vegetative cuttings in a controlled greenhouse environment in Rheinberg, Germany since June, 2017 has shown that the unique features of this new Impatiens plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Impatiens have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature, daylight and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Dongimagmior’. These characteristics in combination distinguish ‘Dongimagmior’ as a new and distinct Impatiens plant:

-   -   1. Upright to outwardly spreading and uniformly mounding plant         habit.     -   2. Vigorous growth habit.     -   3. Freely branching habit.     -   4. Large, glossy and dark green-colored leaves with dark         red-colored midveins and lower surfaces.     -   5. Freely flowering habit.     -   6. Large flowers with cordate-shaped petals that are light         purple in color with a deep red-colored blush on the banner         petal.     -   7. Good garden performance.

Plants of the new Impatiens can be compared to plants of the female parent selection. Plants of the new Impatiens differ primarily from plants of the female parent selection in the following characteristics:

-   -   1. Plants of the new Impatiens are more vigorous than plants of         the female parent selection.     -   2. Plants of the new Impatiens have larger flowers than plants         of the female parent selection.     -   3. Flowers of plants of the new Impatiens are light purple in         color with a deep red-colored blush on the banner petal whereas         flowers of plants of the female parent selection are red in         color with lavender-colored centers.

Plants of the new Impatiens can be compared to plants of the male parent selection. Plants of the new Impatiens differ primarily from plants of the male parent selection in the following characteristics:

-   -   1. Plants of the new Impatiens are more vigorous than plants of         the male parent selection.     -   2. Plants of the new Impatiens have darker green-colored leaves         than plants of the male parent selection.     -   3. Plants of the new Impatiens flower earlier than plants of the         male parent selection.     -   4. Flowers of plants of the new Impatiens are light purple in         color with a deep red-colored blush on the banner petal whereas         flowers of plants of the male parent selection are white in         color.

Plants of the new Impatiens can be compared to plants of Impatiens hawkeri ‘Doimmalaven’, disclosed in U.S. Plant Pat. No. 30,744. In side-by-side comparisons, plants of the new Impatiens differ primarily from plants of ‘Doimmalaven’ in the following characteristics:

-   -   1. Plants of the new Impatiens are more vigorous than plants of         ‘Doimmalaven’.     -   2. Plants of the new Impatiens have darker green-colored leaves         than plants of ‘Doimmalaven’.     -   3. Plants of the new Impatiens have smaller flowers than plants         of ‘Doimmalaven’.     -   4. Flowers of plants of the new Impatiens are light purple in         color with a deep red-colored blush on the banner petal whereas         flowers of plants of ‘Doimmalaven’ are purple to red purple in         color with white-colored centers.

Plants of the new Impatiens can also be compared to plants of Impatiens hawkeri ‘Moorea’, disclosed in U.S. Plant Pat. No. 9,147. In side-by-side comparisons, plants of the new Impatiens differ primarily from plants of ‘Moorea’ in the following characteristics:

-   -   1. Plants of the new Impatiens are more vigorous than plants of         ‘Moorea’.     -   2. Plants of the new Impatiens have larger flowers than plants         of ‘Moorea’.     -   3. Flowers of plants of the new Impatiens are light purple in         color with a deep red-colored blush on the banner petal whereas         flowers of plants of ‘Moorea’ are white in color.
